| Abstract |
This paper proposes a temperature control of the dehumidifier by thermoelectric using the SPI controller. The dehumidifier using thermoelectric module cooled an air by the heat absorption of thermoelectric module, and then removed a water in air using this process. Therefore, the temperature control for the heat absorption side of the thermoelectric module is a very important factor in determining the performance of the dehumidifier. To improve performance of the conventional PI controller which widely used in industrial field, this paper proposes the series connected PI (SPI) controller which can be adjusted an input value of PI controller. The SPI controller proposed in this paper is consisted of the series connected PI controller. The first PI controller adjusted the input value of second PI controller using the teal temperature and the command temperature. The second PI controller controled the temperature using the adjusted input value. In this paper, We compareed the characteristics of temperature control by PI and SPI controllers, and proved the validity of the proposed method. |
